Abstract

Background: Increased body mass index is a known risk factor for increased adverse events post-hysterectomy. The effects of previous bariatric surgery on outcomes after inpatient hysterectomy are not well elucidated.

Methods: The 2016 to 2018 National Inpatient Sample was queried for patients who underwent hysterectomy using International Classification of Disease 10 Procedure Codes before a matched analysis was performed to neutralize the potential confounding effects of comorbidities, body mass index, and age. Patients were divided into the following 2 groups: a case group (those with a history of bariatric surgery) and a control group (those without a history of bariatric surgery). Patients in the respective groups were matched 1:2 by age, Elixhauser comorbidity score, and body mass index at the time of surgery to analyze the risk of complications and mean length of stay.

Results: When 1:2 case-control matching was performed, women with a history of bariatric surgery (N = 595) had significantly fewer complications and decreased mean length of stay than the non-bariatric group (N = 1,190), even after controlling for body mass index at the time of hysterectomy.

Conclusions: When matched for age, body mass index, and comorbidity score, patients with previous bariatric surgery had fewer complications and shorter lengths of stay than patients without a history of bariatric surgery. Women with a body mass index ≥40 kg/m2 requiring non-urgent hysterectomy may benefit from undergoing bariatric surgery first.
